Now to change font color you should click on the toolbars Preferences -> Form Styles
There you will see field "Font Color" clicking on it will show you the color picker so that you can type the color number or select it directly.
Now to change the font type / font family
We are still on the Form Styles, just go a bit above the Font Color
Now there is also another way, which should be quicker to access.
We must first switch to Form Style toolbar
To change color just click on the Font Color button
Similarly do for font type by clicking on Font
